Kramer VS-84UT 8x4 HDMI/HDBaseT 2.0 Matrix Switcher
The KramerVS-84UT is an all-in-one 8×4 presentation system that combines a 4K60 (4:2:0) HDMI/HDBaseT 2.0 matrix switcher, long-reach signal extension, a programmable master room controller, USB extension, PoE on HDBaseT outputs, and a built-in power amplifier. It switches video, embeds/de-embeds audio, and drives both HDMI and HDBaseT displays.
Key Features
- 8×4 4K Matrix: Switches 6 HDMI + 2 HDBaseT inputs to 2 HDMI + 2 HDBaseT outputs at up to 4K60 (4:2:0), HDCP/DVI compliant, with auto-switching and last-state memory.
- HDBaseT Extension + PoE: Extend up to 100 m at 4K60 (4:2:0) or up to 180 m in Ultra mode at 1080p; PoE powers compatible receivers/peripherals.
- Comprehensive Audio: 4 balanced/mic (selectable) + 4 unbalanced stereo inputs, de-embed to balanced outs, and an onboard 2×50 W @ 4 Ω power-amplified output with global AV mute.
- Integrated Control System: Built-in master controller with RS-232/RS-485, IR, GPI/O, relays, K-NET™, and IP—plus embedded web UI, scheduling, and macros.
- USB & Ethernet Tunneling: USB 1.1/2.0 extension (up to 127 Mbps) and extended Ethernet via HDBaseT for streamlined device connectivity.
- Pro-grade Integration: Kramer reKlocking™/EQ for signal integrity, advanced per-input EDID management, and 2U rackmount chassis with universal AC power.
